I know this is neither 2 piece or casting but it works really well for motorcycle/bicycle/fly-in trips. I have a double ice fishing pole case that will hold two 4 piece 14wt fly rods with spinning reals on them. These 14wt flyrods will cast a bait like nobodies business. In fast you can put so much energy into a cast you have to be careful about not snapping the line. They are traditionally used for saltwater, even sharks. So, they have plenty of backbone without feeling like a broomstick. In fact they are excellent for feeling a walleye nibble on a jig and for tying on a steel leader and a 1oz Johnson Silver Minnow and ripping it for Pike.
If you wanted to try one with a casting reel you could get a multi piece 14wt flyrod blank off fleabay or used and either build/rebuild it yourself or have one built with a casting handle.
I’m sure other folks will have plenty of traditional suggestions for you.
Then again what are you trolling for and how deep? You may need a broomstick.
